This paper studies the joint tail behavior of two randomly weighted sums∑_(i=1)^(m)Θ_(i)X_(i)and∑_(j=1)^(n)θ_(j)Y_(j)for some m,n∈N∪{∞},in which the primary random variables{X_(i);i∈N}and{Y_(i);i∈N},respectively,are real-valued,dependent and heavy-tailed,while the random weights{Θi,θi;i∈N}are nonnegative and arbitrarily dependent,but the three sequences{X_(i);i∈N},{Y_(i);i∈N}and{Θ_(i),θ_(i);i∈N}are mutually *** two types of weak dependence assumptions on the heavy-tailed primary random variables and some mild moment conditions on the random weights,we establish some(uniformly)asymptotic formulas for the joint tail probability of the two randomly weighted sums,expressing the insensitivity with respect to the underlying weak dependence *** applications,we consider both discrete-time and continuous-time insurance risk models,and obtain some asymptotic results for ruin probabilities.

Aging and death are unavoidable in life. While immortality may be impossible, many people dream of living a long and healthy life. Throughout history, humans have searched for ways to stay young, but have not found an effective way. This may be because the methods used do not target the causes of aging directly. To address this, we investigated how to delay aging using traditional Chinese medicine (TCM) and Western medicine approaches. In this article, we will explain the causes of aging in the context of TCM and Western medicine and suggest methods to delay it. By integrating TCM and Western medicine, I hope to help everyone age healthily and enjoy a long life.
